1.3 Dimensions of automatic paper cutter

2. Plant Environment, Handling, Installation and Storage

2.1 Plant Environment

There must be a compressed air source outside the equipment installation, and its pressure should be 0.8MPa and above; the ground on which the automatic paper cutter is placed must have a certain level of flatness and hardness, such as cement floor or ceramic tile.

2.2 Storage

When the machine is not used for a long time, it should be stored in a dry, ventilated, free from sunlight, rain and corrosion place, and the surface should be covered with dust-proof devices.

2.3 Carry

2.3.1 To lift the machine correctly and safely, the following principles must be followed:

      - use equipment with sufficient lifting capacity;

      - wrap all sharp edges;

      - Check the safety device attached to the hook;

      - Do not move the load until it is actually lifted.

2.3.2 Work before lifting

      - Make sure all personnel are safely away from the equipment;

      - Make sure that the load will not swing after lifting;

      - determine the safe positioning of all parts that may fall;

      - Lift the machine vertically to prevent it from colliding with nearby objects.

2.3.3 Mobile

   When approaching the destination of the machine's lift, the short movement of the machine can prevent people from pushing the equipment into position, and the person responsible for lifting and lifting must:

   - Clarify the destination of the machine lifting;

   - Command from a position where the crane driver can easily observe;

   - If a dangerous situation occurs, stop the operation immediately (eg someone passes by).

2.3.4 Placement

   Before the machine is placed in place, the ground must be cleaned, and the machine should not be placed near the following places:



   - Power lines.

2.4 Installation method

a) The machine consists of 2 parts, the main part and the band saw part.

b) Place the main unit and adjust the level first, then loosen the screw in the red circle shown in the photo, and pull the shaft out.


c) Link the band saw part to the 2 screw rods of the host (as shown by the red arrow in the figure below), and adjust the blade of the band saw part to the middle of the mold by adjusting the screw rod.


d) After the installation is completed, perform trial cutting through the manual page and observe the verticality of the cutting. If the cutting is inclined, adjust the screw directly to adjust the angle of the blade. After the cutting is vertical, the screw nut can be locked. (The angle of the blade has been ground before the machine comes out. If the cutting is not vertical when the customer installs the machine, it can be adjusted through the link screw of the host and the band saw.)

2.5 Install

a) After the machine is in place, directly adjust the position of each part with a hoist or organizer;

b) Adjust the level, adjust the anchor screws of each part so that the rollers of the machine are on the same level, and then lock each part with the screws.

C) Assemble the individual parts removed from the factory for shipment;

d) Install the electrical control part; (this machine uses three-phase five-wire power supply, the line voltage is 380V, and the voltage fluctuation is within ±5℅; the resistance of the ground wire cannot be greater than 4 ohms, and the three shorter lines are U, V and W are three-phase, marked with "0" as the zero line (ie, the neutral line of the transformer), and the yellow-green two-color line is the ground line.)

e) Connect the air source to the pneumatic triplet; (see Figure 2-5 for the specific connection method)
